OXIDATION-REDUCTION REACTIONS

Chapter 10 OXIDATION-REDUCTION REACTIONS oxidation reduction REACTIONS are those involving the transfer of electrons from one substance to another (no bonding formed or broken). Example: Fe 3+ + e- Fe 2+ Protons (H+) are often involved in these REACTIONS also. Another example of redox REACTIONS is: H2O2 + 2e- + 2H+ 2H2O Rules for the assigning of oxidation numbers 1.

The availability of electrons usually controls the oxidation/reduction reactions and this availability is expressed as redox potentials. Soil microbes often serve as catalysis for the release of electrons from a substance. B. Source of H+ (water). In soils, the main source of protons is water. H2O çŁ H+ + OH-C. Definition 1.

10.9 Redox Reactions Many single replacement, combination, decomposition and combustion reactions are also redox reactions. Redox is short for reduction and oxidation. Reduction is when an element’s charge goes down and oxidation is when an element’s charge goes up. Note you can’t have reduction without oxidation and vice versa.
